IMPROVEMENT IN HOOKS AND EYES FOR TACKLE-BLOCKS.

Specification forming part of Letters Patent No. 136,833, dated March18, 1873.

To all whamjt mag "concern:

Be it known that. I, J 015m HOLROYD, of the. city and county ofWashington, in the Distriet of Columbia, have invented a new, use- 7forming part of this specification.

The nature or essence of my invention con- I sists in turning the nib orpoint of the hook from the block so that it will catch against the underside of the eye and prevent the hook from unhooking and hold the blockhorizontally, or in such an angle or position as may be. desired.

Figure 1 of the accompanying drawing is a side elevation of atackle-block and hook and eye with my improvements. Fig. 2 is a plan ofthe same.

In the above-mentioned drawing, A is a tackle-block, which may have oneor more sheaves. This block may be made of metal or of wood, andstrapped with metal, the strap being extended at the head of the blockto form the hook B, which is bent around so as to pass through the metaleye 0, and the point is turned or bent from the block to form a nib, D,which catches under the eye 0 and holds the block in a horizontal plane,and allows it to swing either way in the horizontal plane, but will notunhook, unless the tail of the block is raised up to about an angle offortyfive degrees, when the book may be taken out of the eye andreplaced when required.

The above-described improvement is adaptedto gun-tackles--that is,tackles for training guns, and for other service about a ship, where thehauling is horizontal or but little inclined. m, e p,

What I'claim as my invention and impfive ment in hooks fortackle-blocks, is-

\ Turning the nib or point of the hook from the block, substantially asdescribed, so that it will catch against the under side of the eye andprevent the hook from unhooking, and hold the block horizontally or atsuch an angle or position as may be desired.

JOHN HOLROYD.
